These nucleotides can then be further processed to form the pyrimidine bases found in DNA and RNA. The pyrimidine biosynthetic pathway is tightly regulated to ensure the proper balance of nucleotides ...

ACIDIC degradation has been widely used to determine the distribution of the pyrimidine nucleotides in deoxyribonucleic acids (DNA; I). Two main methods have been used; in one the DNA was treated ...

The purine structure consists of a pyrimidine ring (positions 1 to 6) fused to an imidazole ring (positions 7 to 9). Adenine and guanine, the two most common purines in DNA and RNA, share this core ...
